If something manages to set the maximum file size to MAX_OFFSET+1, this
can cause the xfs and ext4 filesystems at least to become corrupt.
Ordinarily, the kernel protects against userspace trying this by
checking the value early in the truncate() and ftruncate() system calls
calls - but there are at least two places that this check is bypassed:
(1) Cachefiles will round up the EOF of the backing file to DIO block
size so as to allow DIO on the final block - but this might push
the offset negative. It then calls notify_change(), but this
inadvertently bypasses the checking. This can be triggered if
someone puts an 8EiB-1 file on a server for someone else to try and
access by, say, nfs.
(2) ksmbd doesn't check the value it is given in set_end_of_file_info()
and then calls vfs_truncate() directly - which also bypasses the
check.
In both cases, it is potentially possible for a network filesystem to
cause a disk filesystem to be corrupted: cachefiles in the client's
cache filesystem; ksmbd in the server's filesystem.
nfsd is okay as it checks the value, but we can then remove this check
too.
Fix this by adding a check to inode_newsize_ok(), as called from
setattr_prepare(), thereby catching the issue as filesystems set up to
perform the truncate with minimal opportunity for bypassing the new
check.
Fixes: 1f08c925e7 ("cachefiles: Implement backing file wrangling")
Fixes: f441584858 ("cifsd: add file operations")

devm_regulator_get_optional() API will return -ENODEV if the regulator was
not found. For the optional supplies CX, PX we should not fail in that case
but rather continue. So let's catch that error and continue silently if
those regulators are not found.
The commit 3f52d118f9 ("remoteproc: qcom_q6v5_pas: Deal silently with
optional px and cx regulators") was supposed to do the same but it missed
the fact that devm_regulator_get_optional() API returns -ENODEV when the

- Rework copy_oldmem_page() callback to take an iov_iter.
This includes few prerequisite updates and fixes to the
oldmem reading code.
- Rework cpufeature implementation to allow for various CPU feature
indications, which is not only limited to hardware capabilities,
but also allows CPU facilities.
- Use the cpufeature rework to autoload Ultravisor module when CPU
facility 158 is available.
- Add ELF note type for encrypted CPU state of a protected virtual CPU.
The zgetdump tool from s390-tools package will decrypt the CPU state
using a Customer Communication Key and overwrite respective notes to
make the data accessible for crash and other debugging tools.
- Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto test.
- Fix incorrect recovery of kretprobe modified return address in stacktrace.
- Switch the NMI handler to use generic irqentry_nmi_enter() and
irqentry_nmi_exit() helper functions.
- Rework the cryptographic Adjunct Processors (AP) pass-through design
to support dynamic changes to the AP matrix of a running guest as well
as to implement more of the AP architecture.
- Minor boot code cleanups.

the process taking the glock. This moves unnecessary complexity out
of the core glock code. Clean up the instantiate logic to be more

This reverts commit 4bf7fda4dc.
It turns out that it was hopelessly naive to think that this would work,
considering that we've always done this. The first machine I actually
tested this on broke at bootup, getting to
Reached target cryptsetup.target - Local Encrypted Volumes.
and then hanging. It's unclear what actually fails, since there's a lot
else going on around that time (eg amdgpu probing also happens around
that same time, but it could be some other random init thing that didn't
complete earlier and just caused the boot to hang at that point).
The expectations that we should default to some unsafe and untested mode
seems entirely unfounded, and the belief that this wouldn't affect
modern systems is clearly entirely false. The machine in question is
about two years old, so it's not exactly shiny, but it's also not some
dusty old museum piece PDP-11 in a closet.

DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
than mutex for its locking.
- Add optional "try_verify_in_tasklet" feature to DM verity target.
This feature gives users the option to improve IO latency by using a
tasklet to verify, using hashes in bufio's cache, rather than wait
to schedule a work item via workqueue. But if there is a bufio cache
miss, or an error, then the tasklet will fallback to using workqueue.
- Incremental changes to both dm-bufio and the DM verity target to use
jump_label to minimize cost of branching associated with the niche
"try_verify_in_tasklet" feature. DM-bufio in particular is used by
quite a few other DM targets so it doesn't make sense to incur
additional bufio cost in those targets purely for the benefit of
this niche verity feature if the feature isn't ever used.
- Optimize verity_verify_io, which is used by both workqueue and
tasklet based verification, if FEC is not configured or tasklet
based verification isn't used.
- Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
"try_verify_in_tasklet" is specified.

As diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a
bunch of new drivers (as usual), while there have been some
significant (but almost invisible) improvements in ALSA core
side, too. Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user
won't notice, but on the devices with tons of control elements,
it can be visibly faster
- Support for input validation for controls; this will harden
for badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer
in situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some
board integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
WAS883x, and Texas Instruments TAS2780
HD- and USB-audio:
- Continued improvement for CS35L41 (sub)codec support
- More quirks for various devices (HP, Lenovo, Dell, Clevo)

- Introduce 'perf lock contention' subtool, using new lock contention
tracepoints and using BPF for in kernel aggregation and then userspace
processing using the perf tooling infrastructure for resolving symbols, target
specification, etc.
Since the new lock contention tracepoints don't provide lock names, get up to
8 stack traces and display the first non-lock function symbol name as a caller:
$ perf lock report -F acquired,contended,avg_wait,wait_total
Name acquired contended avg wait total wait
update_blocked_a... 40 40 3.61 us 144.45 us
kernfs_fop_open+... 5 5 3.64 us 18.18 us

tick_do_update_j... 1 1 6.04 us 6.04 us
ep_scan_ready_list 1 1 3.93 us 3.93 us
Supports the usual 'perf record' + 'perf report' workflow as well as a
BCC/bpftrace like mode where you start the tool and then press control+C to get
results:
$ sudo perf lock contention -b

This reverts commit 7d06fed77b.
This introduced vmem_mutex locking from vmem_map_4k_page()
function called from smp_reinit_ipl_cpu() with interrupts
disabled. While it is a pre-SMP early initcall no other CPUs
running in parallel nor other code taking vmem_mutex on this
boot stage - it still needs to be fixed.

Pull MM updates from Andrew Morton:
"Most of the MM queue. A few things are still pending.
Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.

In this cycle we add PCI support to OpenRISC used in our new QEMU virt
platform. The base of this series is a merge of Bjorn's PCI headers
cleanup branch and 5.16-rc6. The patches from the PCI branch are needed
for the series to work.
The main updates from me include:
- Kconfig updates to support OpenRISC PCI (just config now after the
PCI cleanups I did on Bjorn's branch)
- A new defconfig for the qemu virt platform.
- Also there is one MAINTAINERS update. As I was working on the PCI
series we kept getting bounces from Richard's old email address. I
added this here; I am not sure how these are usually handled when
the maintainer doesn't queue it themselves.

There are three independent sets of changes:
- Sai Prakash Ranjan adds tracing support to the asm-generic
version of the MMIO accessors, which is intended to help
understand problems with device drivers and has been part
of Qualcomm's vendor kernels for many years.
- A patch from Sebastian Siewior to rework the handling of
IRQ stacks in softirqs across architectures, which is
needed for enabling PREEMPT_RT.
- The last patch to remove the CONFIG_VIRT_TO_BUS option and
some of the code behind that, after the last users of this
old interface made it in through the netdev, scsi, media and
staging trees.

These updates came in after I had already tagged the branches,
but they still seem appropriate for 6.0 and most of them were
part of linux-next through other trees.
- The reset controller tree adds one new driver for the TI TPS380x
power management chip and a few minor changes in other drivers
- Apple M1 now has a DT entry for the NVMe controller after the
driver was merged, and has a new mailing list in the MAINTAINERS
file.
- Fixes for USB on the Socionext Uniphier platforms and the
network controller on Intel Cyclone5.

One real bugfix to change the io_pgetevents_time64() syscall to use the compat
implementation when running in compat mode, otherwise the signed int32
parameters min_nr and nr will be incorrectly handled as unsigned int64 values.
Other than that just small cleanups:
* hardware database housekeeping and proper /proc/iomem output
* add proper function exit code if probe functions fail
* drop stale variables (pa_swapper_pg_lock)
* drop unneccessary zero-initializations
* typo fixes in comments
